LODE error when using owlapi=true

[jetschni]

Hello

i get the following error when using the parameter owlapi=true e.g. localhost:9030/lode/extract?owlapi=true&url=https://localhost/test.rdf)

LODE error
Reason: Could not find an ontology storer which can handle the format: org.semanticweb.owlapi.io.RDFXMLOntologyFormat@1b0bc2f

I followed the steps described in readme.md, the examples are working fine. The rdf file is fine as well, tested with http://www.essepuntato.it/lode/owlapi/http://domain.com/test.rdf

Hi Jonas, would you please provide me with the original source file you used for that, so as to be sure to reproduce your issue locally?

Hey Silvio, thank you very much for your answer. Of course: https://bmake.th-brandenburg.de/services/odoc/ITCat/SchemaGraph.rdf

For the hosted version it's working fine: http://www.essepuntato.it/lode/owlapi/https://bmake.th-brandenburg.de/services/odoc/ITCat/SchemaGraph.rdf

Hey Silvio,

could you figure out where the problem is?

Hi @jetschni,

I've investigated a bit few days ago, and it seems that the version of the OWLAPI that is used (by means of running the mvn command) is the last one – which would be dinamically downloaded by maven. However, I have to change this behaviour so as to constrain the use of a specific version, that is the one adopted by the online version of the tool available at http://www.essepuntato.it/lode.

However, I honestly don't have any time in the following days to investigate it further. If you think you can help me with this, just give me a shout!

Have a nice day :-)

FYI Tried almost all 3.4 and 3.5 versions of

net.sourceforge.owlapi

                    <artifactId>owlapi-distribution</artifactId>
                    <version>3.4</version>

still the same problem. Using version 4.x i get exception java.lang.AbstractMethodError at org.semanticweb.owlapi.io.OWLParserFactoryRegistry.getKey(OWLParserFactoryRegistry.java:176) any ideas?

Encountering the same problem:

When using the example listed in the README.md: http://localhost:8080/lode/extract?owlapi=true&url=http://www.loa.istc.cnr.it/ontologies/DOLCE-Lite.owl

gives the following error:

@essepuntato : you mention that maven selects the latest library. That's not true, versions of all libraries are hardcoded in the pom.xml file. If you know which versions are used by the online tool, it's as simply as replacing those versions.
